Word Problems (WP) - pg 79 (Ex. with men and women) - Before I read about the "unknown multiplier," I added the 3 and 4 and got 7. And then created a ratio with 3/7 = x/56 to figure out how many men there were. Can you do this?

[tommywallach]

Indeed. Your method works great here. That said, I'd encourage you to learn the unknown multiplier method, because it's much more generally applicable (i.e. it helps out on a lot of ratio questions where your method wouldn't work).

Good luck!
